To all whom t may concern:

.Be it known that l, RICHARD SIEGERT,

a sub'ect of the Free State of Saxony, German epublic, 3 Free State of Saxony,

have invented a new and, useful Process and Ap aratus for the Manufacture of 'Hollow bjects of Chocolate, of which the following is a specification.

The present invention has for its object a process and an apparatus for the-manufacture of hollow objects' of chocolate, as for instance small animals, balls, eggs and gures of an kind.

First of a ,the process form-ing the object 'of the present invention consists in that double-moulds partly filled with liquid chocolate-mass are inserted into receptacles and a planetary motion is imparted to said receptacles so that the latter are subject to a .rotary movement in a vertical plane and simultaneously to a rotary movement round their longitudinal axis. Said ,process is,

secondly, still extended in that the receptacles containing the double-moulds illerl with liquid chocolate are, during their planetary motion, subject tol `a springing or jumping movement in the direction of the longitudinal axis of said receptacles.

The employment of the planetary-movement of the receptacles filled with doublemouldscontaining liquid chocolate tends to prevent any thickened and settled parts 'within the chocolate-mass to betransformed into figures, and allows regulation of the speed used for the apparatus perform the process forming the object of the present invention within wider limits than with the4 apparatus of similar kind 40 known up to the presen in which the transition from a slow rotation usually required to a very high one is always accompanied by diiculties. c

A favorable and very uniform distribution of the chocolate-mass inserted into the double-moulds is also obtained and ensured by a springing or jumping movement'im- German Republic,

llo

parted to the Areceptacles containing the' partly filled double-moulds during their 5 planetarymotion,sa1d springing o r jumping movement causing a special shaklng of the chocolate-mass prior to and during the contact with the walls of the separate doublemoulds, said contact being the result of the and a resident of Dresden.;L

arranged to centrifugal- Iower actuated against the receptacles. y said shaking movement of the mass the latter within the double-moulds and becomes of highly uniformv density and structure or grain. v

As stated above, the process in question can still further =be improved by exposing the chocolate-mass contained within the' double-moulds and subjected to the combined planetary and springing or jumping movement to a cold air draught for the purpose of cooling said moulds as quickly as ossible.

he apparatus for performing the process of manufacture of hollow chocolate-bodies forming the object of the present invention consists in the arrangement of a series of receptacles or containers (two at least) 'for receiving the doubl-moulds partly filled with liquid chocolate-mass, each of said rcceptacles or containers being connected under spring-pressure to a shaft suitably' rotated. All receptacles are mounted on the periphery of a disc fastened to said shaft horizontallyy arranged and suitably rotated for inst-ance by a pulley. In this manner, all receptacles are rotated together in a vertical plane.

New, for the purpose of imparting, during said vertical rotary movement of the receptacles, a rotary movement to the latter round their longitudinal axis, a planet-wheelv series is arranged, consistin of a bevel-gear stationarily arrangedround the shaft mentioned and a number of ,bevel-gears (two at least) engaging said stationary bevel-gear and fastened each on the vertical axis of each receptacle. For causing a springing or jumping movement of the receptacles during their plan- 'etary motion a clutch consisting of two parts engaging one into another is arranged be tween each receptacle and the disc carrying it. One part of the clutch is fastened to the periphery of the flanged disc, and the `other part rotates during the rotary movement of the axis ofthe receptacle and slides by its teeth over the teeth of the stationary clutchpart. During movable clutch-part is raised springing" or .jumping movement of each separate receptacle.

An example of construction of an appais uniformly distributed said sliding movement the and causes ay r performing the process for the facture oi'hoiicw or chocola"` according to the present invention is shown in the drawinglq annexed the specil is a sideeieeation apparatus and 2 a iongitudinal elevationoif arranged in combination with e jacket or casing through which a draught ci' coolingair or 4other cooling-medium is supplied tor the purpose oi' cooling the monlds as quickly as possible during or after the moulding 'of the chocolate-mass contained therein. Fig. 3 is a transverse section ci the casing through line AB of Fig. 2 and Fig. fi a horizontal section of the casing through line @D in Fig. 2 Figure 5 shows in front elevation partly in section a detail of the construction of the device for imparting a springing action to the receptacles e.

a is the frame ot the apparatus and b the shaft horizontally mounted in the upper part of t e frame mentioned. :fastened to one extremity of the shaft b, on the other extremity of which a anged disc a' is mounted. The iiange and the hub ci the disc ci form bearings for the shafts el of a number of receptacles e arranged with a perforated wall formed, for instance, of wiregauze, said receptacles containing a number of double-moulds partly lled with liquid chocolate-mass, According to Figs. l and 2 only two receptacles e diametrically arranged one to another are shown. In case of more than two suchreceptacles they are arranged in a star-like manner on and round the anged disc a?.

Said disc d. carrying the receptacles e is rotated in a vertical plane by the rotary movement of the shaft b., Now, to rotate, during the rotary movement of said receptacles, the latter round their own axes (planetary motion), each of the bevel-gears f is mounted on the respective shaft el of the receptacles e, said bevel-gears engaging a bevel-gear i stationan'ly arranged round the shaft b and fastened to the frame of the apparatus. The shafts e1 areso arranged as slide in a longitudinal direction through the bevel-gears 7.

The operation oiz the parts mentioned above is as follows:

During the rotary movement of the shaft b,

the anged disc d mounted on it and the receptacles e arranged with their shafts e1 on the periphery of said disc are rotated in a vertical plane also. The receptacles mentioned are fastened to the shafts e1 by trunnions g in such a manner that they may partake of the rotary movement of the shafts mentioned.

A yielding bolt It suitably fastened to each of the receptacles prevents an unintentional disengagement of the latter from their shafts e1.

c is a pulley a fast The parts shown detail in Fi f" serre to combine with the planetary movement of the receptacles e an adr springing or jumping movement., .es ci seen from said ligure representing of the device temporarily situated abortl a.. horizontally' mounted shaft the bevel-gear gf is loosely'arranged on the shaft e"- adjustably connected with the letter by groove and tongue. The bevel-gear f engagn ing the stationary bevel-gear t is provided in its lower part with a central circular groove, lwhereas a disc t is fastened by e splint t1 to the shaft e1 near its lower` end. A sprin l is inserted between the dise t and the beve -gear f in such a manner that during the rotaryjmovement of the danged disc ci the bevel-gear f is rotated by its engagement with the stationary bevel-gear z' (liig. i). Together with said rotary movement the shaft el, is rotated, taking with it the upper clutch-part c. During said rotation the teeth of the clutch-part slide along the teeth of the stationary clutch-part 701 and are simultaneously raised so as to raise the shaft el, thereby compressing the spring Z. li? the lower points of the teeth oi the upper clutch-part lc have reached and surpassed the upper points of the teeth of the lower stationary clutch-part Isl, the spring Z acts against the disc t and moves the latter in a downward direction in such a manner that the teeth of the upper clutch-part fall again into the interstices between each two teeth of the lower clutch-part cl.

The procedure described is repeated in succession and thus the springing or jumping movement of the receptacles is obtained and ensured.

Now if it is intended to cool the chocolate mass contained within the double-moulds as quickly aspossible during and after the moulding-procedure of the mass, the apparatus described is surrounded by a sheet iron jacket or casing for supplying a cold air draught towards the receptacles rota ing withln said jacket shown inFigs. 2, 3 and 4.

m is the sheet iron jacket or casin and n a pipe arranged near the bottom o? it and supplying a draught of compressed cold-air into the passage or conduit o decreasing in section towards its upper part. The wallof the acket m situated on the side of the rotating receptacles is in an open connection with the interior of the jacket by slots p to which the cold air draught is directed by the guiding plates g into the interior of the j aoket m.

The left-hand part of the jacket or casing m is provided with doors r which can be moved round the hinges s, s1, whereas the right-hand part of said jacket is in the shape of a closed hollow chamber, in which the receptacles together lwith the partly filled double-moulds are rotated and the compressed cooling air is made use of for` a very` rapid cooling down of the contents of the moulds.

The assage or conduit o may be replaced by coo ing pipes transmitting their .cold to the moulds of the receptacles rotating within the jacket or casing, vwithout departing liquid chocolate-mass, inserting said filled jumping moulds in receptacles, imparting a planetar motion to said receptacles, imparting to t e latter simultaneously with said motion a springing or jumping movement and cooling down the contents of the doublemoulds during their planetary motion by a coolingA medium. f
